Quick start for Ingress

Quickly expose your app to the Internet by creating an Ingress resource.

Create a Kubernetes ClusterIP service for your app so that it are in the router load balancing.
```
oc expose deploy <app_deployment_name> --name my-app-svc --port <app_port> -n <project>
```

Get the Ingress subdomain for your cluster.

ibmcloud oc cluster get -c <cluster_name_or_ID> | grep 'Ingress Subdomain'

Example output

Ingress Subdomain:      mycluster-a1b2cdef345678g9hi012j3kl4567890-0000.us-south.containers.appdomain.cloud

Using the Ingress subdomain, create an Ingress resource file. Replace <app_path> with the path that your app listens on. If your app does not listen on a specific path, define the root path as a slash (/) only.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: myingressresource
spec:
  rules:
  - host: <ingress_subdomain>
    http:
      paths:
      - path: /<app_path>
        pathType: ImplementationSpecific
        backend:
          service:
            name: my-app-svc
            port:
              number: 80

Create the Ingress resource in the same project as your app service.
```
oc apply -f myingressresource.yaml -n <project>
```
In a web browser, enter the Ingress subdomain and the path for your app.
```
http://<ingress_subdomain>/<app_path>
```
